Northern Lights autoflower outdoor

I went on a holiday for a few days so I couldn't take any pictures from day 8-13. I left the plant under the two CFL's the whole time (24hrs on) and asked someone to move the lights further away if it grew too tall. To my surprise this baby had grown a whole lot in the last couple days without me taking care of her. She's 26 cm (10 inch) wide and about 11 cm (4.3 inch) tall. The weather around here is still pretty bad for this time of the year, always cloudy, so I think I will keep her inside for another week. Hope the sun will start pushing through after next week :p I'm also thinking of giving the first nutes, 'Plagron alga grow' at about 1ml/l or should I wait? As always any advice is welcome!
